BATTERY HAND LAMP.

Application ed October 10, 192'?.

My invention relates toa battery hand lamp and consists of a dry cell battery having an incandescent bulb in a removable holder so constructed as to be capable of being flipped by the thumb or finger into either the operative or the inoperative position.

It is an object of my invention to provide an improved battery hand lamp Which is It is a further object ot' my invention to provide a battery hand lamp which cannot be accidently lighted thus overcoming an objection encountered in lamps of this class. Further objects and advantages Will be made clear by the following detailed description, which is to be taken in conjunction With the accompanying drawings, wherein Fig. 1 illustrates in part sectional elevation the Whole of the battery hand lamp with the incandescent bulb in solid lines or the operative position and in dotted lines for the inoperative position;

F 2 is a perspective view ofthe incandescent bulb in its holder;

Fig. 5 is a sectional view of the upper end of the battery showing a modified form ot' cup;

Fig. 6 is a perspective view of another form ot the invention showing the lamp removed;

Fig. 7 is a vertical, sectional view ot the 'form shown in Fig. 6, and,

Fig. 8 is a sectional view of another torni ot' the invention.

In the form of the invention shown in Figs. 1 to 4; of the drawings, I enclose a battery conY sisting ot one or more dry cells, 1 and 2, electrically connected, as by connector 3, in a suitable carton Il, Which may be of paper, and Which projects above the top of thel dry cells to form an oval cup. In this cup I place a metallic cup 5, Which is electrically connected to one of the poles oi' the battery, preferably by soldering to the negative can, as at 6. An opening 7, in the bottom of the metallic cup 5 allows the other pole, preferably the positive 8, to be exposed. The second pole must be insulated from the cup, as by a sheet ot insulating paper 9. The side edges of opening 7 are bent up, as at 10, for the purpose to be explained hereinafter. At the end of the Serial No. 225,045.

cup opposite to opening' 7 Wings 11 are formed as by punching in the sides of the cup 5, the purpose of these Wings to be explained hereinaftcr. A small lug 12 is formed on the bottom ot the cup at the end removed from opening 7, as by stamping the metal.

rihe incandescent bulb 13, Fig. 2, is mounted, by soldering, in a holder which consists ot a sheet metal backing 14, to which is hailed a looped spring 15 preferably made of Wire. The holder pivots on this bail when the holder is flipped from the operative to inoperative position and vice versa. The lovrer portion or base of the backing 14 is provided with flanged supports 16, so shaped as to assist in the operation of the device, which Will be explained hereinafter. rlhe holder cooperates ivith the battery having the cup 5 mounted as described by slipping the looped spring Wire 15 underneath Wings 11 and over lug 12 so that the base of bulb 13 contacts with the terminal of the battery exposed through openings 7 as shown in solid lines in Fig. 1. The pressure of Wings 11 on looped spring Wire 15 insures a good contact between the base of the bulb and the exposed pole of the battery. Since the cup 5 is electrically connected to one pole of the battery at 6, electrical connection is made to the screw thread 17 of the lamp through the holder Which is in contact at various points With the cup. lhen the holder is in the operative position, the flanged supports 16 are positioned on the outside ot the bent up side edges 10 and are thereby prevented trom slipping into opening 7. To put the hand lamp in the inoperative position, the backing 14 is iiipped forward to the position shown by broken lines in Fig. 1, the bulb 13 then being at right angles to the operative position. The looped spring 15, which is in practically the same position as when the holder is in the operative position, in cooperation with the lug 12 prevents the backing 14 from rubbing against the cup 5 While the holder is being changed from one position to another. Since the base ot' the bulb is no longer in contact with exposed terminal 8, the bulb is no longer lighted. The looped spring 15 still acts to keep the holder of Fig. 2 lirmly in position. The projecting portion of the flange 16 is so shaped with a relatively square corner that when the holder is flipped into either the operative or inoperative position it assumes such position With a snap since the spring pressure is greatest at the intermediate position. This insures the holders beineV in either the operative or inoperative position and, furthermore, prevents the holder from being readily pushed into the operative position to accidently light the bulb while being carried in the pocket or elsewhere. When the holder is in the inoperative position, the backing 14C covers the top ot the cup and acts as a closure. Furthermore, since the backing 1li now rests upon wings 11, as shown in dotted lines in Fig. 1, the bulb is protected against injury by shock during the act of dipping the holder into the inoperative position or in the event that the hand lamp is accidently struck against a rigid object. lVhen in the operative position, backing 14 acts as a reflector. Lip 18 projects slightly above cup 5 to aid the linger or thumb in flipping the holder into the operative position.

Fig. 5 illustrates an alternative `form of construction in which the metallic cup at the top of the hand lamp is dispensed with in favor ot a metallic plate 18, termed, positioned, and functioning as the bottom ot cup 5, Fig. 3. In this construction, a rugged casing 19, of insulating material encloses the dry cell battery and extends above the top thereof to form the cup into which the incandescent bulb holder is inserted The tune` tion of turned in wings 11 of Fig 3 is performed by a suitable rod 2O of Fig. 5 rigidly held in the sides of the casing. The method of maintaining the electrical circuit in this hand lamp is the same as described in the first mentioned construction.

Figs. 6 and 7 illustrate another form of the invention in which one or more dry cells 21, positioned preferably one above the other, are connected in series the whole being encased in a cylindrical, octagonal or other suitably shaped metal easing 22. The upper end ot the casing is recessed or punched to torni a cup 23 similar to the cup described in connection with Figs. 1 to P) of the drawings. A tube 24 oit suitable insulating material may be arranged between the cells and the metal casing. The bottom ot' the easing may be closed by a threaded cap 25 having a spring 26 which is adapted to contact with the bottom of the zine can ot the lower cell and thus connect the holder et cup 23 to one pole ot the battery through the casing 22. The incandescent bulb holder 14 is adapted to be mounted in the cup 23 in the manner heretofore described and permit contact to be made between the carbon 'pole 27 ot the upper cell and the base terminal of the lamp bulb in the manner heretofore described.

In the form of the invention shown in Fig. 8 of the drawings, I employ a casing 2S formed of paper or other insulating material. A metal sleeve or ring 29 is arranged adjacent the lower end of the casing and is provided with external threads to receive the cap 25. A conductor strip 30 is arranged between the spring 26 and the bottom of the Zinc electrode ot the lower cell. This strip ei;- tends upwardly between the outer easing 28 'and the insulating sleeve 24 and is connected to a cup S1 similar in construction to the cup 5 heretofore described. As the construction of the hand lamp shown in Fig. S is cylindrical in cross section, the recessed portion'ot the cup extends from a point adjacent the center to one edge similar to the construction shown in Fig. G of the drawings. The outer periphery of the cup 31 is flanged as at- 32 and is then extended downwardly as at over the exterior ot the easing QS. At suitable intervals the tlange o'lf the cup may be punched into the paper or other material forming the casing 28 as indicated at 84 to anchor the cup in position.

The operation of the device will be apparent from the foregoing description. The lip 18 permits the user to insert his linger or thumb under the outer edge of the holder and swing it on its pivot to place the lamp in operative position. The holder then serves as a reflector. The wings 16 form a wiping contact with the bottom of the cup 5 and thus insures a goed electrical conneetion between the terminal of the lamp and the cell. The base terminal or' the lamp likewise moves across the other pole ot the battery making a. wiping contact lllhen the lamp is in closed position holder 14 acts as a cover or closure and -protects the incandescent bulb rom injury.
